NITED STATES IMPROVEMENT IN OlL-STOVES.

Specification forming part of Letters Patent No. 167,237, dated August31, 1875; application filed July 31, 1875.

CASE B.

To all whom it may concern:

Be it known that I, FREDERICK GATES, of Frankfort, in the county ofHerkimer and State of New York, have invented a new and usefulImprovement in Oil-Stove, of which the following is a specification:

Figure 1 is a vertical longitudinal section of a portion of an oil-stoveillustrating my in- Fig. 2 is a detail cross-section of the lower partof the'same taken through the line ac :r, Fig. 1.

Similar letters of reference indicate corresponding parts.

The objection of this invention is to furnish an improved oil-stove,which shall be so constructed as to be used for boiling, baking, androasting articles of food, as may be desired, and which shall beeffective in use and reliable in operation when used for either purpose.

The invention will first be described in connection with drawing, andthen pointed out in the claims.

A is the case that incloses the lamp and its chimney. The case A is maderectangular in form, andof such a size as to inclose one, two,

or more lamps, as may be desired. In the front side of the case A isformed an opening of such a length and height that the lamp or lamps maybe readily put in and taken out through it, and which is closed by thedoor B.

' The door B is hinged at its upper edge, andis made of perforated sheetmetal, so that air may pass through it in suflicient quantities tosupport combustion. In the upper part of the front of the caseA isformed an opening of such a size that the chimneyorchimneys may bereadily put in and taken out through it, and which is closed by. a door,0. The door 0 is hinged at its side edge, and is made of perforatedsheet metal to allow air to pass through it. To the inner surface of thecase A, and in the same plane with the space between the doors B O, issecured a hollow deflector, D, to deflect the air and cause it to passdown into the lamp, and then up into the cones of the lamp-burners. Theinner edge of the hollow deflector D is open, and holes are formedthrough the outer part of its lower plate, so that-a portion of the airmay pass through the cavity of the deflector D, and be projected againstthe outer surface of the lamp-chimney. In the top plate of the case Aare formed two or more boilerholes, a to receive the vessels in which.boiling or frying is to be done. To the under side of the top plate ofthe case A, between the boiler-holes a are attached one or moredeflectors, E, which are made V-shaped to divide the current of heatedair and deflect it toward the boiler-holes a. The inclined sides of thedeflector E are provided at their ends with inclined flanges e to assistin guiding the heated air more directly toward the said boiler-holes I aIn the upper part of the ends of the case A are formed holes a for theair to escape through, so as to keep up a circulation. F are platesattached to or formed upon the top plate of the case A, or the upperpart of the ends of the said case A, which project down at a littledistance from the ends of the case A, and the lower edges of which are alittle below the said holes (0 so that the heated air, after passing upto the boiler-holes a must descend a little before it can escape throughthe holes (0 so that there will always be a stratum of hot air in theupper part of the case A. When the stove is to be used for baking orroasting purposes a grate, G, is placed upon the top plate of the caseA, and which is provided with flanges or short feet to raiseit a littleabove the said top plate. In this case the grate G is surrounded by abox, H, the walls of which are made double to prevent the too rapidradiation of heat. In the upper part of the inner walls of the box H areformed holes h through which the heated air passes into the spacebetween the walls of the box H, through which the heated air passes downand escapes through the holes h inthe lower part of the outer walls ofthe said box H. In the outer wall of the top of the box H are formed afew holes, 79,- so that a portion of the heated air may escape in thatdirection. In this way a circulation will be kept up, and at the sametime the escape of the heated air will be checked sufficiently to enableboxH to be thoroughly heated. The lower edge of the box H is made with arabbet or flange to keep it in place upon the top of the case A. The boxH is provided with a handle, I, to enable it to be conveniently put onand taken ofl".

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the doors B 0, made ofperforated sheet metal, with the lower and upper parts of the front ofthe case A, substantially as herein shown and described.

2. The combination of the plates or flanges F with the upper part of thecase A through which the holes a have been formed, substantially asherein shown and described.

3. The combination of the deflectors E 6 with the top plate of the caseA, and with the boiler-holes a substantially as herein shown anddescribed.

4. The combination of the grate G and the box H, made with double walls,and provided with the holes h b h with the top of the case A of anoil-stove, substantially as herein shown and described.
